I've seen some posts about doing something with box 11 to see if TT will take the "s" designation but it hasn't worked for me. I searched for typical mistakes on entering W-2's and saw something on the Internal Revenue website saying a common mistake is to use "s" for a simple 401(k) and the correct code for a simple 401(k) is code "d". I entered the "d" and the W-2 worked fine. So, this is probably not a "fix" but it does make it so you can file the return. My wife's w-2 does indicate "s" on it, so this would be done just to get past whatever is wrong with TT and/or the government approving the forms.
